Question:
Two questions regarding penguins: (1) do they have teeth? and (2) what is their life span?



Replies:
Hi Kate!

1) No, penguins do not have teeth, and
2) they live from 15-20 years in the wild and up to 30 years in a controlled environment (like at an Aquarium). Like other birds, penguins use their bills to capture and manipulate the small fish that they eat. They use their bill to turn the fish around so it's head-first before the penguin swallows it (this prevents the bird from injury on the spines of the fish's fins). Thanks for asking!
